Here's how to watch tonight's second US presidential debate

It's Hillary Clinton vs. Donald Trump: Round Two, and there will be no shortage of interest given just how much has changed in the Race to the White House over the past few days.

The Republican candidate comes into this debate with his campaign in a state of crisis, and after a poor performance in the first debate, it looks like things aren't going to get any easier for Trump as the pair prepare to face off again.

The second debate takes place in Washington University in St. Louis, but will be in a town-hall format meaning the questions will come from moderators Martha Raddatz of ABC News and CNN's Anderson Cooper, as well as members of the audience in attendance.

Television

If you're prepared to stay up late (or set a very early alarm) and watch the debate, then you have plenty of options to watch events unfold live on television.

Sky News (as well as Sky Atlantic) will be showing the debate, with the channel starting their coverage with build-up and analysis at 1am. Other news channels, such as NDTV 24x7 and Al Jazeera will also be showing it.

Channel 4 will have coverage of the debate, starting at 1.35am, while BBC News, as well as BBC One will be covering the debate live from 2am.

Repeats will be shown on Sky News and NDTV 24x7 in the morning, if you prefer to stay in bed on Sunday night.

Live stream

Given that the debates are simulcast across a number of channels in the United States (ABC, CBS, NBC, CNN, CNBC, Fox, Fox News, MSNBC, PBS and Univsion), you should have no trouble finding a live stream on their website or social media channels, with many of the stations choosing to drop their usual sign-in or geoblocking procedures.

Online publications and newspapers such as Politico, The Washington Post, Bloomberg and others will be streaming via their websites.

Social media will have a role to play in this debate too, with Twitter live streaming the spectacle, allowing you to weigh in with your own comments and thoughts on the debate. A number of publishers will also make use of their Snapchat profiles to share snippets of the debate, and using Facebook Live before and after to provide context, reaction, and buildup.

YouTube will also have a number of live streams of the debate to keep you in the loop, one of which is embedded below.

Anything else?

If you happen to have a VR headset, then you can enjoy a 360 livestream of the debate thanks to NBC, through AltspaceVR, an app available for Oculus Rift, Samsung Gear VR and HTC Vive.

If you'd prefer not to watch and simply put on a pair of headphones from the comfort of your bedroom instead, then you can listen live on NPR or through an international radio app such as TuneIn.
